OPTICAL COMMUNICATION TRANSMISSION LINE

摘要

PURPOSE:To provide the optical transmission line of a practical optical soliton transmission system which substitutes for conventional dynamic soliton transmission. CONSTITUTION:The optical communication transmission line controls the transmission of light soliton pulses by controlling the wavelength variance of an optical fiber 2 being the transmission line at every long section including plural amplifiers 3. In concrete, a section 5 wherein the mean value of the wavelength variance of the optical fiber 2 is relatively larger than a variance value meeting soliton requirements and a section 6 wherein the mean value of the wavelength variance is relatively smaller are combined and alternated to obtain so as to let a mean variance value over a long transmission distance be a positive valve, thus controlling the transmission of the light soliton pulses.
